The Edit: Space-A travel is a free military benefit that lets eligible service members, retirees, 100% disabled veterans, surviving spouses, and their dependents fly on military aircraft with available seats. It is also called Space Available travel, MAC flights, or military hops. Flights on military cargo aircraft are free. Flights on the Patriot Express, a chartered commercial aircraft, cost about $40 per person in international taxes. Travelers are placed in six priority categories, with Category 1 being the highest priority and Category 6 the lowest. Sign-up is allowed up to 60 days before travel at most terminals. Schedules are released 72 hours in advance for cargo flights and 30 days in advance for Patriot Express flights. This guide covers eligibility, sign-up, schedules, packing, what to expect at Roll Call, baggage rules, parking, and what to do after you land.

Here is a quick 8 step guide to get you started. Each photo is linked to a video where I explain exactly what you need to do in each step. If you’d like to watch my entire playlist on the space available travel program it’s on Instagram, Tiktok and Youtube. Otherwise, this guide is broken into a few sections to get you started.

Space-Available flights, also known as “MAC flights” or “military hops,” are operational military flights with extra available seats. The primary focus for the military remains the mission first, where Space-A passengers are secondary. You can essentially think of yourself as extra cargo getting to snag an open seat when they’re released.
Don’t ever expect to catch flights with 100% certainty. Although, Depending on certain mission routes it may be easier to gauge what flights frequently go to certain places. Here are just a small few examples of flights we have been able to catch by watching & planning on frequently scheduled routes:
Routes will change as the mission does but generally you’re able to rely more on a patriot express flight over the 72-hour schedule. These are the two main methods you will be able to determine what flights you will be able to compete for.

First Step, you’ll want to make sure you understand your category placement. You can take a deeper dive into your specific category here to see a complete listing of eligible members of the military community that are authorized to fly.
Space-A passengers fall into six categories known as “CATS,” with 1 being the top tier and 6 representing the lowest priority.
Most people get tripped up here, especially Cat 6 travelers, because where you can fly depends on which kind of Cat 6 you are. Here’s the cheat sheet:
All Cat 6 travelers can bring accompanying dependents (with proper ID).
Source: DoD Instruction 4515.13, Air Transportation Eligibility
| Who You Are | Where You Can Fly |
|---|---|
| Retirees (20+ years served, drawing retirement or Medical Retiree) | Anywhere. CONUS, OCONUS, and foreign countries |
| 100% P&T Disabled Vets (not retired from military) | CONUS plus territories. Hawaii, Alaska, Guam, Puerto Rico, USVI, American Samoa |
| Gray Area Retirees and Reservists (under 60, not yet drawing retirement pay) | CONUS plus territories. No foreign country travel |
| Surviving Spouses (of retirees or active duty service members) | CONUS only. Lower 48 states |
If you’re not sure which bucket you fall into, your USID card will tell you. Retired members will see “RETIRED”. That’s your golden ticket. Vets with the “100% American Disabled Veteran” designation are in the second tier. When in doubt, ask your local DEERS office before you sign up.
If you’re Guard or Reserve, your eligibility depends on your current status, and there are three of them:
Activated for 30+ days? You’re treated as active duty. Cat 1 through 3 like any other AD service member.
Drilling reservist (training for points or pay, on the Active Status List)? You can fly Cat 6, but only within CONUS and to/from U.S. territories (Hawaii, Alaska, Guam, Puerto Rico, USVI, American Samoa). No foreign country travel. You’ll need your CAC plus a completed DD Form 1853 (“Verification of Reserve Status for Travel Eligibility”) signed by your unit commander.
Gray area retiree (retired Reserve/Guard under 60, not yet drawing pay)? Same rules as drilling reservists. CONUS plus territories, no foreign travel. Once you hit 60 and start drawing retirement pay, you convert to full retiree status, and at that point you can fly anywhere Space-A goes, including foreign countries.
If any of this is changing for you (you’re about to turn 60, your unit just activated you, you’re transitioning out), update your DEERS record before you sign up. Terminal staff go off your USID card affiliation, so make sure your card reflects your current status.
If you’re a military spouse or dependent thinking about flying Space-A without your sponsor, the rules depend entirely on what your sponsor is doing. Here’s the cheat sheet:
| Your Sponsor’s Situation | Your Category | Where You Can Fly | Paperwork You Need |
|---|---|---|---|
| Deployed 365+ days | Cat 3 (bottom of the list) | Anywhere Space-A flies, including foreign countries | Deployment orders plus sponsor’s command letter |
| Deployed 30 to 364 days | Cat 4 | Anywhere Space-A flies, including foreign countries | Deployment orders plus sponsor’s command letter |
| Stationed OCONUS, command-sponsored (you live there with them) | Cat 5 | OCONUS to CONUS, OCONUS to OCONUS within theater. CONUS-to-CONUS only if manifested through to OCONUS | Command Sponsor Letter from sponsor’s commander |
| Stationed OCONUS, you are not command-sponsored | Cat 5 | OCONUS to CONUS only | Letter from sponsor’s installation commander |
| Active duty on EML orders, you are unaccompanied | Cat 4 | OCONUS to CONUS or within theater | EML Memo (unfunded EML form for Pacific Command or Europe Command) |
| Active duty home in CONUS, not deployed | Not eligible to fly unaccompanied | N/A | N/A |
| Retiree, not deployed | Not eligible to fly unaccompanied | N/A | Spouse must travel with sponsor |
| 100% P&T disabled vet, gray area retiree, or surviving spouse | Not eligible to fly unaccompanied | N/A | Spouse must travel with sponsor |
Letters are valid for 90 days or one round trip, whichever comes first. You’ll need a new letter for each trip beyond that. Source: DoD Instruction 4515.13, Air Transportation Eligibility, Section 4, Table 3.
The most important thing to understand: your category and your geographic restrictions both depend on what your sponsor is currently doing, not on your relationship to them. A retiree’s spouse cannot fly unaccompanied even though the retiree can fly anywhere. An active duty spouse with a deployed husband can fly anywhere Space-A goes. The military rules treat the sponsor’s situation as the variable, not the family member’s status.
As the retiree in our family, I’m Alex’s sponsor. The kids and Alex travel as my dependents, which means they need me with them on Space-A flights. Most blogs assume the sponsor is the husband, but in our case it’s me. Alex and/or the kids are eligible to fly but can not fly alone without me accompanying them.
Special situations like foreign spouses, green card holders, or dependents with special needs have additional rules. Full breakdown coming in our Flying Space-A Without Your Sponsor deep dive.
Often you’ll be asked what category you fall in and you’ll want to know this for the sign-up process in Step 3.
You can watch my video explaining the first step here. For a more in-depth explanation on how Categories work and what you’re most likely to be in, see the “How Does Military Space A Flights Work” section below.
After knowing your category you’ll submit your sign-up. Keep a copy of this. It expires after 60 days. The best way to sign up that I recommend is e-mailing, over using their online sign-up but I’ll link both below so you can make the decision to do what’s best for you.
TIP: You’ll want to include all military passenger amc terminals you may depart from or arrive at for travel. This isn’t you signing up for a specific flight but more just letting the terminal know your intent that you’re ready to be placed in the 60 day queu
The signup window is 60 days, so most people assume you should sign up the very first day you’re eligible. That’s not actually the best move.
Here’s why: your priority within your category is set by your signup date. If you sign up 60 days out, you’re competing against everyone else who signed up 60 days out. Including the people who signed up before you. But your signup also expires after 60 days, which means if you sign up too early, your window closes before you’re done traveling.
The sweet spot is signing up 45 to 50 days before your hoped for travel date. You still have priority within your category against most other travelers. And your window stays open long enough to cover your full trip.
If your trip is going to span more than 60 days from your original signup, you have to re-sign up every 60 days to stay active. Set a calendar reminder.
Pro tip from the most expensive mistake we see: The moment you’re manifested on your outbound flight, sign up for your return at every passenger terminal you might come back through. We recommend signing up for your return roughly 2 weeks after your outbound signup so the windows overlap correctly. Don’t wait until you’ve landed to think about getting home. By then, you’re starting from zero priority while everyone else has been signed up for weeks.

Once you’re signed up, the next skill is reading the schedules. Every passenger terminal posts their flights to their own page on the AMC Passenger Terminal Directory and there are actually two different schedules you need to know about:
The 72-Hour Schedule shows the next three days of cargo missions (C-17s, C-5s, KC-135s, the works). These are your free flights. Schedules drop daily, sometimes twice daily, and yes… They change last minute. Don’t fall in love with a flight 48 hours out.
The 30-Day Schedule shows Patriot Express flights. The chartered, commercial style planes for the upcoming month. These are more predictable but they cost a small per-person tax (around $40 international, see Step 4).
The piece most newbies miss: a lot of terminals also post a Roll Call Report. This is gold. It shows you historical data. How many seats were actually released on recent flights, the lowest category that got picked up, and how many passengers were competing. If you see a recent flight to your destination released 45 seats and the lowest category that made it on was Cat 6 with a sign-up date from a week ago? You have a real shot. If they released 5 seats and the latest sign-up was two months back? Pack a backup plan.
One quick translation note: schedules use Zulu time (also called UTC or GMT). When you see “1430Z” on a roll call report, that’s 2:30 PM in London, not your local time. From the East Coast that’s 9:30 AM, from Hawaii it’s 4:30 AM the same day, from Germany it’s 3:30 PM. Always do the math from Zulu, never assume local. Some reports also use the Julian calendar for dates: “165” means the 165th day of the year (June 14 in a non-leap year). Don’t let either throw you. Don’t let it throw you.
For a full walkthrough of every column on every schedule type, including the Seats Released vs. Seats Used distinction and how to spot a competitive flight before you drive 8 hours to the terminal. Read Alex’s How to Find and Understand Space-A Flight Schedules guide. It’s the single highest leverage skill in Space-A travel.
But if you don’t have time, here’s the rule of thumb: East coast continues east to Europe out of bases like Dover, BWI, Norfolk, and McGuire. West coast goes west to Hawaii and Japan out of Travis, JBLM, and SeaTac.

Watch the video for Step 3 here: Watch Step 3
Once you’re signed up and start seeing flights you might catch, it’s time to prep for roll call.
Roll call is the official selection of passengers for each flight, based on category and sign-up date. You MUST be present (in-person or via remote sign-in, depending on the terminal) and ready with all your documents.
What to bring:
*There are extra required forms depending on your category please check there or call the passenger terminal for verification before showing up for roll call.
And don’t forget your bags:

We linked everything for you on our ShopMy. Use this as a general guide to mash up things you already have in your home for the trip.
On all Space-A flights you’ll be required to wear closed toed shoes. Also, sometimes these flights can get cold so a light blanket or jacket may help you be more comfortable too.
Here’s a packing move that changes long Space-A flights from suffering to actual rest: a queen-size inflatable mattress, rolled into a small duffel, counts as one of your two checked bags. On a C-17 with floor space, you can blow it up after takeoff and sleep horizontal for 8 hours.
The math is simple. You’re allowed two checked bags up to 70 pounds each. An inflatable mattress weighs 2 pounds rolled. That’s 60+ pounds of “checked bag” capacity left over for your actual stuff. You’re not giving up anything to bring it. We’ve used ours on six different missions across the Pacific.
What you need:
This works best on C-17s and C-5s where there’s open floor space behind the seats. It does not work on the Patriot Express (assigned seats) or KC-135s (no floor room). And it doesn’t work on every C-17 flight either. Sometimes the cargo configuration eats up the floor space. Have it as a backup plan, not a guaranteed bed.
If the floor is full and you can’t blow it up, the mattress works as a backrest in webbed seating. Either way, it’s earning its luggage spot.

Each Person is allowed two pieces of luggage up to 70 pounds and 62 linear (length+width+height) inches each. Plus one, 45-linear inch, hand-carried item, e.g. small suitcase, garment bag, backpack. This item must fit under the seat or in available overhead compartments in the cabin area. You’re also allowed, One hand-carried, personal item, e.g. cosmetic case, purse, briefcase. Anything carryon plays by TSA rules. You can also “pool” luggage meaning per family if there’s 3 people you’ll have up to 6 checked items allowed.
Simply put: Each person can have 2 checked bags, 1 carryon and 1 personal item.

Space-A flights happen on two types of aircraft. The Patriot Express and Rotator (Scheduled Military flights) are generally released publicly 30 days in advance of the departure date. Where organic military aircraft flights happen consistently and will show on the website under the 72 hour flight schedule:
Each has pros and cons, but both can get you across the globe for nearly nothing.
You’ll either fly regular cargo military flights (72-hour schedule) or you’ll fly through the Patriot Express (30-day schedule). Both are great options that come with their own set of Pros & Cons. I will explain them below.

When flying on the Cargo Planes you’ll most likely be flying on a C5 or C17 and sometimes even the C130 and the KC-10. There’s also rare occasions when you may be put onto a different aircraft. Once we were put onto a DV(VIP) plane and it was awesome. I think the mystery can be somewhat fun. The military has an extensive fleet of aircraft that you may be placed on. Again everything is mission dependent so that is why the military aircraft can very.
The flights are released 72 hours in advance and will be located and labeled as such on the Passenger Terminals website. Each Passenger Terminal is solely responsible for updating their own flight schedule. A more step-by-step written process is located below and also in Step 2 of the Quick Start Guide above.
For the most part the military (dod aircraft) grey tailed missions are FREE ? We have gotten to Germany twice completely free by flying there on C-5 missions.
We recently got to Asia completely free from Washington too. Stopping in Guam, Japan and Singapore because all the flights we took were grey tailed missions. If you’d like to watch our Space-A to Asia Vlog series it’s on Tiktok. We show you exactly how that went the good, bad and ugly.

When flying Patriot Express missions you’re essentially going on a fancier commercial plane. These are chartered flights that the military pays for that feel like you’re on a commercial airline. Mostly the mission for the Patriot Express (PE) flights are to help members of the uniformed services in relocating. They help PCSing military families be able to PCS easier compared to going the traditional route through a major commercial airline. More information can be found here in the Patriot Express brochure.
These are essentially the same thing except they’re not chartered. They can be commercial aircraft still but are usually military aircraft. The main thing to note is that these fall under the 30 day flight schedule and are usually operated under the military side of things vs contractor.
These are posted generally at the beginning of each month and will be located on the 30 Day Flight Schedule and will be located on the Passenger Terminals website. Each Passenger Terminal is solely responsible for updating their own flight schedule. A more step-by-step process is located below.

The cost of the Patriot Express is based on where you’re flying to and from. If going from Europe back to the United States it’ll cost you $40.03 Per Person (International Head Tax Fee $22.10 + FIS $17.93 ). Grey Tailed missions are generally free, see above.
When we did our military space a flights to Europe a few months ago from Travis Air Force Base (California) to Germany we were on a grey tailed mission. It was free. Coming home we flew the Patriot Express from the United Kingdom to BWI. Then took another grey tailed mission from the East Coast back to Travis. Total travel costs for our round trip airfare (family of 4) was $146.60 usd in 2023. Today in 2025 a family of 4 would cost: $160.12.
Here’s the breakdown costs for (2026):
Generally these flights are a little more reliable so you can plan better for a super cheap flight utilizing it. You get inflight entertainment, better meals and the seats are generally more comfortable than the C-17’s & C-130’s.
They’re assigned seating. If you get put in Economy seating and the flight is full it’s going to be like flying commercial with not much space to move around. Younger kids & animals are on these flights with parents who are overwhelmed. These flights have a longer Roll Call Period of waiting around an additional 1-2 hours before leaving on top of the 2-3 hours it usually takes after Roll Call. You’re paying the Head Tax.

Watch the video for Step 5 here: Watch Step 5
Once you land, your adventure isn’t over. Now you need to actually exit the base, and that sometimes can be tricky.
Here’s a strategy that experienced Space-A travelers use that most newbies miss: when you’re flying a mission with multiple stops, get manifested all the way to your final destination, not just the next stop.
If you catch a PE from Seattle to Yokota with stops in Iwakuni and Kadena, and your goal is Kadena, ask the terminal staff to manifest you all the way to Kadena at the original Roll Call. You stay on the same boarding pass through every stop. You don’t get off at Iwakuni and re-compete for seats, you stay on the plane.
This matters most on the routes where the intermediate stop is more competitive than your final destination. For example: the Travis to Hickam to Yokota route. Hickam is one of the most competitive Space-A spots in the world during summer PCS season. If you get manifested through to Yokota at Travis, you skip the Hickam Roll Call entirely. You arrive in Yokota having only competed once.
There’s only one situation where you can lose a “manifested through” seat: if a duty passenger needs your seat for a leg you haven’t flown yet. Those are rare, but they do happen. Otherwise, manifesting through is one of the strongest moves in the Space-A playbook.
We just recently did this from Kadena (Okinawa) back to Hickam (Hawaii) with a stop in Anderson (Guam). It can be long though because you don’t usually get off the aircraft you’ll want to plan extra snacks and entertainment.
You’ll know if you’re manifested by what’s on your boarding pass. Verify the final destination is correct with the agent and that you’re eligbile to do this. Don’t assume.
Things to know:
Pro Tip: Download the GRAM for the base before takeoff
A lot of the Passenger Terminals have something called a Travel Gram. If you’re headed to a location where you may not have Data Coverage consider downloading this ahead of time. If a terminal has one it’ll be located on their terminal page. I have also included them into the interactive map to make accessing it easy for you.
Watch the video for Step 6 here: Watch Step 6
There’s no snack cart in the sky on most military aircraft. Here’s what to expect:
🎯 Pro tip: Always bring your own snacks, even if you think you can order a box or have meals. Delays and swaps happen often and nobody wants to fly hangry.
On Grey tailed missions they generally cost $6 Per boxed lunch. Usually, you’ll get a main course like a sandwich or chicken strips, chips, fruit, something sweet like a multi-grain bar, a bottle of Soda and a bottle of water. Honestly I don’t think they’re bad but they can get old quick if you’re taking several hops back to back. We bring a collapsable bag of extra snacks and a refillable water bottle with us to kind of break up the food on travel days. Check out my video below to see an example of what’s in a Box.
How it works: Once manifested for the flight, the service counter will ask for payment. This is usually done when checking your bags and getting your boarding ticket. Generally it’s best to have cash on you in case their card reader isn’t working. Most of the time the major terminals have an ATM. After you board the aircraft, the meals will arrive. Usually the flight crew passes them out before takeoff, but sometimes will pass them out shortly after take-off.
Watch the video for Step 7 here: Watch Step 7
Flying Space-A usually means long, one way travel… so where do you park your car?
🚗 Pro tip: Always snap a photo of your license plate in advance so you have it with you if you’re selected for a flight. It will save you a trip from having to run back out to get it.
Most Terminals have a 30 day rule allowing you to leave your vehicle parked in their designated parking lot. If you need longterm parking try to get that figured out ahead of time. Regardless, You’ll want to check the Passenger Terminals rules on leaving your vehicle. Time frames vary depending on each terminal. You really don’t want any surprises the day you’re trying to fly out or after coming back.
When flying Space-A, flexibility matters. Renting a one-way rental car gives you options if you fly out of one base and return through another, or if your plans shift last minute.
We almost always use Enterprise for this because of their nationwide locations, easy one-way bookings, and military-friendly policies. It’s one of the simplest ways to avoid being stuck or backtracking just to return a car.
You can read exactly why we use Enterprise for Space-A travel in our full review here.
Watch the video for Step 8 here: Watch Step 8
Even seasoned travelers mess this up. Here’s what to watch for:
🧠 The truth? Space-A works best when you treat it like a flexible strategy, not a sure thing.

Many Passenger Terminals offer family lounges, which is a huge plus when flying Space-A with kids. These lounges often include toys, play areas, private nursery spaces, refrigerators, and nearby restrooms, making long waits much more manageable for families.
Children 11 and older are required to carry their own military ID issued through DEERS. Younger children can typically fly with a passport or birth certificate. We also recommend printing out benefit numbers for all military dependents ahead of time (available through MilConnect) and keeping them with you just in case.
If you’re traveling as a family, we share practical, real-life advice in our tips for flying Space-A with kids post, including what to expect at terminals and how we handle long waits with children.
We don’t have pets. We have never flown with them ourselves, but we have seen a ton of families do it. Flying Space-A with pets is allowed when under orders for PCSing. Service Animals are also allowed to fly with you. There are specific requirements the AMC terminal will need and expenses will be on you, here’s more information linked HERE.
Space-A is one of the best benefits the military offers. But it isn’t always the right call, and the people who get burned by it are usually the ones who tried to force it into a trip that didn’t fit. Here’s when we don’t recommend it:
If you need to be somewhere by a specific day: a wedding, a cruise departure, the start of school, a funeral, your own kid’s birthday… fly commercial. Space-A passengers are the lowest priority on every flight. Even if everything looks good 24 hours out, the mission can change, the seats can disappear, or the flight can fall off the schedule entirely. We’ve seen it happen to people who absolutely needed to be somewhere. Don’t be that family.
Space-A travel needs flexibility. Both directions. If you only have 10 days off and you spend three of them trying to catch a flight out, then another two trying to catch one back, you’ve burned half your vacation in passenger terminals. For shorter trips, the math just doesn’t work. Save Space-A for the trips where you can flex by a few days on either end.
This is the busiest time of year for Space-A and not because more leisure travelers are flying. It’s because every PCSing family is taking their seats. Active duty members on orders are higher priority than anyone in Cat 4–6, and they fill up the Patriot Express flights especially fast. If you’re a retiree or 100% disabled vet trying to get to Europe in July? Expect to compete with hundreds of duty travelers and their families. Possible? Yes. Likely to get the first flight out? No.
Christmas, New Year’s, Thanksgiving, and Spring Break are the second toughest windows. Same logic. Too much demand, not enough seats. If your kid has two weeks off school and you want to use it to see Hawaii? Plan around the actual school break, not in the middle of it.
Some military aircraft have baggage weight limits as low as 30 pounds per person. If you’re traveling with kids in car seats plus checked luggage plus the camera gear plus the gifts for grandma… you might not even be eligible for the flight. Pack-light flexibility is part of the deal.
Kids traveling without their sponsor have specific rules and exceptions. Pets (other than service dogs) can’t fly Space-A at all, only on PCS orders. If your trip depends on bringing the dog, this is likely not your best option.
Use Space-A when: you have flexibility, time, and a sense of adventure. Skip it when: you have deadlines, kids on tight school schedules, or a non-negotiable end date. The whole point of this benefit is that it’s free and free comes with strings. Knowing which strings matter to your trip is the whole game.
New to Space-A? Click any term to expand the definition. This is the cheat sheet we wish we’d had on day one.
The Air Force command that runs most Space-A passenger terminals worldwide. The AMC website (amc.af.mil) hosts terminal directories and flight schedules.
The lower 48 states. Does NOT include Hawaii, Alaska, or U.S. territories. Important for understanding Cat 6 geographic restrictions.
Anywhere that’s not the lower 48. Includes Hawaii, Alaska, all U.S. territories, and all foreign countries.
Space-A travelers are placed in 1 of 6 categories. Cat 1 is highest priority (emergency leave). Cat 6 is lowest (retirees, vets, surviving spouses). Within a category, priority is by signup date.
The moment terminal staff announce who got selected for a flight. You must be physically present and “marked present” before Roll Call begins. Show up at least 1-2 hours early for cargo flights, 3 hours for Patriot Express.
Once you have your boarding pass and your bags are checked in, you’re “manifested.” That means you’re confirmed on the flight. Manifesting “all the way through” means you’re confirmed to the final destination of a multi-stop mission, not just the next stop.
Chartered commercial-style aircraft that the DoD pays for to move military families. Looks and feels like a regular commercial flight (assigned seats, in-flight meals, jetway boarding). Has a small per-person tax for Space-A travelers (about $40 international).
Same thing as the PE, technically. Some terminals and travelers use “rotator” interchangeably. The 30-day flight schedule shows both PE and rotator missions.
The actual military planes — C-17s, C-5s, KC-135s, KC-10s — that fly Space-A missions. Free for Space-A passengers (no tax). No assigned seating, no in-flight meals (you can buy a $6 box lunch in advance), webbed or jump seating along the sides.
Each terminal posts the next 3 days of cargo flights with destinations, Roll Call times, and tentative seat counts. Updates daily. Subject to change without notice.
Each terminal with PE service posts the upcoming month of PE missions. Shows date and destination but NOT seat counts. Seat counts only become known 72 hours before each flight.
Some terminals post a record of recent flights showing how many seats were released, how many were used, and the latest signup date that made the cut. Use this to gauge how competitive a route is before you commit.
The military ID card. All Space-A travelers age 14+ need one. The affiliation block (“RETIRED,” “100% DAV,” “Active Duty – DEC”) tells terminal staff what category you belong to.
Required paperwork for drilling reservists and gray area retirees flying Space-A. Verifies your active reserve status. Signed by your unit commander.
A specific leave type for service members and dependents stationed in remote/hardship locations. EML travelers get higher Space-A priority (Cat 2 or 4 depending on circumstances). Requires specific paperwork.
Military move from one duty station to another. PCS travelers fly under orders, not Space-A. The two systems are different — PCS travel is funded and guaranteed; Space-A is free but never guaranteed.
Short-term duty assignment away from the home station. Permissive TDY (like for house hunting) qualifies for Space-A under specific categories. Active TDY does not — you’d fly funded.
Coordinated Universal Time. The military and aviation world uses Zulu time on schedules so there’s no confusion across timezones. “1430Z” means 2:30 PM in London. Always do the math from Zulu, never assume local time.
Some Roll Call reports list dates as 1-365 (the day of the year) instead of month/day. “165” means the 165th day of the year (June 14 in non-leap years).
A document some passenger terminals publish covering local logistics — base lodging, ground transport, customs, area info. Download before flying to a base you’ve never been to. Especially useful at OCONUS terminals.
The military’s database of all eligible service members and dependents. Your DEERS record determines your USID card eligibility. Update DEERS whenever a family status changes (marriage, divorce, kid’s birthday, retirement transition).
When you fly Space-A into Japan, Korea, or other countries with SOFA agreements, you may receive a SOFA stamp instead of a regular passport stamp. This entry method has different rules for what you can do in country and how long you can stay.
This is our gift to the Space-A community, completely free. Every military passenger terminal in one interactive map that lives right on your phone through Google Maps. No app to download, no subscription, no paywall. This is the exact map we use when we travel.

That’s it. Every terminal is pinned, color coded by command group, and loaded with contact info, hours, emails, and GRAM links. I’ll keep adding lodging, transport, and local tips for each base as we go, so the more you check back the more useful it gets.
Below are the most-asked Space-A questions from our community and the AMC’s own FAQ. If you have a question not answered here, message us on Instagram @SaltyVagabonds.
Space-A Passengers who fall within the 6 categories (Cat1-Cat6).
Travelers on emergency leave hold Cat 1 status, securing the highest priority for Space-A travel
For recreational travel: Active duty service members, with or without dependents, on environmental morale leave (EML) fall into Cat 2. While those on ordinary leave are categorized as Cat 3 for Space-A travel.
Family members of military personnel traveling alone are designated as either Cat 4 or Cat 5, contingent upon the situation.
Space-A Category 6 encompasses various passenger groups. Retired service members, Reservists, Veterans rated as totally and permanently disabled due to a service-connected disability (100% disabled veterans), and Surviving spouses of deceased service members/retirees. Specific travelers in Category 6 face limitations on their Space-A flight destinations, see below.
Also, the mentioned list of eligible passengers isn’t comprehensive. Additional passengers, including specific civilians within the Department of Defense, may qualify for military space-available travel under different conditions. For a complete listing of eligible passengers check out table 3 in section 4.11.
No. Only service dogs are allowed on Space-A flights, and even those have specific paperwork requirements. Personal pets and emotional support animals are not eligible. The only exception is if you’re flying under PCS orders (not Space-A), in which case pet travel is governed by separate AMC rules. Full AMC pet travel info here.
Not technically required, but bring one anyway. U.S. territories don’t require a passport for U.S. citizens, but Space-A is unpredictable. You may end up routed through a foreign country to get to your destination, especially if you’re flying in summer or to a busy hub. We always travel with our passports even for “domestic” Space-A trips.
For kids under 14 traveling to U.S. territories, a state-issued ID, passport book, or passport card all work. See our post on kids’ ID rules for the full breakdown.
Space-A is free, voluntary, and never guaranteed. PCS travel is funded by the military, mandatory (you have to move), and guaranteed. They use some of the same aircraft (especially Patriot Express), but you’re a different kind of passenger.
If you’re a service member on orders, you fly PCS. Family vacations, leisure trips, and retiree travel are all Space-A. The two systems are governed by different rules and you can’t switch between them mid-trip.
Cargo flights are completely free. Patriot Express (PE) flights have small fees:
$22.10 international head tax
$17.93 federal inspection fee
$5.00 domestic segment tax (for CONUS Patriot Express segments)
$11.10 domestic tax for Hawaii/Alaska routes
~$40 total per person for an international PE leg
$0–$10 if you order a boxed meal on a cargo flight
There’s no fare. The full cost of getting from CONUS to Europe and back via Space-A for our family of 4 has been around $160 in fees flying the Patriot Express and $0 when flying grey tailed missions.
It depends on your sponsor’s status. If the sponsor is deployed or stationed OCONUS, the spouse can often fly unaccompanied with proper paperwork. If the sponsor is a retiree or stationed CONUS without deployment, spouses cannot fly alone.
We have a full breakdown of unaccompanied dependent travel coming. The quick version: see the table at the top of Step 1.
Yes, with the “100% DAV” designation on your USID card. You can fly within CONUS and to/from U.S. territories (Hawaii, Alaska, Guam, Puerto Rico, USVI, American Samoa). You cannot fly to or from foreign countries. Your accompanying dependents (with proper ID) can travel with you.
Authorized disabled veterans (100% DAV) and their dependents (when accompanied by their sponsor) can travel in the continental united states (CONUS). They can also fly directly between the CONUS and Territories (Reference 4515.13 Air Transportation Eligibility page 46).
1. Alaska
2. Hawaii
3. Puerto Rico
4. The U.S. Virgin Islands
5. Guam
6. American Samoa
They can also travel within Alaska, Hawaii, Puerto Rico, or the U.S. Virgin Islands once they’re there. Note: Guam and American Samoa travelers may transit through Hawaii or Alaska to reach their final destination.
Reference: DoD Instruction 4515.13, Section 4, Table 3, Item 47.
Yes, but only within the contiguous 48 states (CONUS only). Surviving spouses of retirees, active duty members who died on duty, and Reserve/Guard members who died on inactive duty or annual training are all eligible under DoD Instruction 4515.13. The CONUS only restriction is in the regulation as written.
No. Only your DEERS listed dependents are eligible. Parents, siblings, ex-spouses, and other relatives who are not your dependents cannot fly Space-A under your sponsorship. Same applies to friends and adult children who have aged out of dependent status.
45 to 50 days before your hoped-for travel date is the sweet spot for most travelers. Earlier than that and your 60-day window may close before you finish your trip. Later than that and other passengers have higher priority within your category. See Step 1 for the full strategy.
You don’t usually get bumped after you’re manifested for cargo flights. Once you’re checked in with a boarding pass, the only thing that may displace you is a duty passenger emergency, which is rare. On Patriot Express flights, you can occasionally be bumped between Roll Calls if duty passenger check-in shifts. Otherwise, manifested usually means confirmed. If you are bumped from the flight, your signup status stays the same and you can choose to compete for another upcoming flight or not.
Sometimes yes, sometimes no.
Space-A works best when:
1. You have flexibility on dates (5+ day buffer either way)
2. You’re traveling in fall, winter, or early spring (not PCS season)
3. You’re hopping between bases that have known regular missions
4. You can pack light and adjust plans on the fly
Space-A doesn’t work when:
1. You have a hard arrival deadline (wedding, cruise, school start)
2. You’re traveling during summer PCS season or major holidays
3. You’re flying with weight or gear you can’t reduce
